Basic knowledge of color science

The second color (three) to mix any two kinds of color, you can get three: orange, red and yellow) purple (red and blue) and green (blue and yellow)

The third color (mixed color) 6 kinds of color on the color wheel is called the mixed color. They are the primary colors and a nearby mixture of indirect color: orange, yellow and orange), green, yellow and green), green (green and blue) crimson (red and orange).

The three elements of color: hue, to distinguish all kinds of color, such as red, green, blue, etc.; Purity, in a show of colour shades; Lightness, in order to show color light and shade.

1, the color match colors

Based on the hue of the color matching is based on the color wheel to think, to use similar colours on the color wheel to match colors, can get a stable and unified feeling. The color with the color of the distance, can achieve certain contrast effect.

Similar hue of the color, can show common color impression. This color on the hue is both commonality and have change, it is very easy to get the color balance. For example: the combination of yellow, orange, orange; Group of the combination of cyan, blue purple, violet hue are similar color. Similar to the color, the same hue hue of the color is easy to produce drab feeling, so you can use contrast color of color matching technique. Poor color contrast in both lively and not conflict, is loved by people of color.

Hue contrast color, it is to point to in the color wheel, is located in hue rings at the ends of the diameter of the circle color or color combinations of remote location. It contains the difference in the color hue, contrast color hue, complementary color hue. Contrast hue of the color properties is green, so often in tonal on or area used to achieve the color balance.

Hue of the color in 16 color wheel, Angle of 0 ° or close to the color, is called the same color hue.Angle is 22.5 °, between the two color color color difference is 1, called the adjacent color hue.Angle 45 ° between the two color, the color difference is 2 color, called a similar color hue.Angle is 67.5 ° and 112.5 °, color difference is 6 ~ 7 color, called hue contrast color.About Angle is 180 °, the color difference is 8 color, is called complementary color hue.

2, tonal color

A. the same tone color

The same tone color is the same color of different colors together to form a relationship of color matching. The color of the same color, the color of purity and lightness its homogeneity, according to the hue lightness slightly change. Different color can produce different colour impression, put together all pure hue, or produce lively sense; The baby clothes and toys are given priority to with light color. In hue contrast and difference in color, usually use the same color of color matching technique, more easier for color harmony.

B, a similar tone color

Adjacent or close to a similar tone color is tonal the picture of two or more than two tonal collocation of color matching together. Similar tone color characteristics is subtle differences between color and color, with the same color have change, won't produce dull sense. Will be dark and dark tonal collocation are together, can produce a feeling of both deep and dark and dark, bright color and strong color and bright color, can produce bright and lively colour impression.

C, contrast color match colors

Contrast color matching is far apart the tonal collocation of two or more than two color together. Contrast color because of the characteristics of the color difference, can result in distinct visual contrast, there is a kind of "contrast" or "rejected" power balance, and thus can produce contrast harmonic. Compare the tone color in the color choice, will have with the horizontal or vertical differences of lightness and purity. For example: light and deep tone color, is the deep and shallow contrast; And bright-coloured tonal with grey tonal collocation, can form the differences on the purity of color matching.

Use the same color of color matching technique, more easier for color harmony.

3. The lightness color

Lightness is one of the important factors, the color changes in brightness can reflect the stereo feeling and the sense of distance of things. Such as the Greek sculpture is through the effect of light and shadow has produced many black and white and grey correlation, formed a sense of accomplishment; China's traditional Chinese painting is also often used without the lightness color is tie-in. Have a color object will also receive the influence of light shade effect. Like purple and yellow has obvious brightness difference.

Lightness can be divided into tall lightness, in lightness and three types of low lightness, such brightness have tall lightness with tall lightness, tall lightness, tall lightness with low lightness in brightness, lightness distribution in lightness and lightness distribution of low lightness and low lightness paired with a pair of low lightness of six. With tall lightness with tall lightness, lightness distribution in lightness and low brightness with low lightness, belonging to the same color lightness. Generally use the same lightness, hue and purity change color. Tall lightness distribution of the lightness and brightness with low lightness, belongs to a slightly different color lightness. Tall lightness color with low lightness belongs to the lighting degrees.
